Explanation:

In case of methyl alcohol , i.e. , CH₃OH ,

counting the equivalent protons , there are three protons of the methyl group at are all equivalent , and shows the chemical shift at 3.4 - 4.0 ppm , there is the increase in the chemical shift value due to the presence of an electronegative oxygen atom .

And there is one more hydrogen atom in the alcoholic functional group , and this hydrogen will also show a chemical shift at 5.0 - 5.5 ppm .

Therefore ,

Methyl alcohol will show two signals due to methyl proton and another due to OH hydrogen .

Atoms of metals tend to1) lose electrons and form negative ions2) lose electrons and form positive ions3) gain electrons and for

timofeeve [1]

Answer:

2) lose electrons and form positive ions

Explanation:

Metals are generally electropositive elements due to the fact that they lose electrons to their non-metal counterparts and hence, form CATIONS or positively charged atoms. Non-metals, on the contrary, gains electrons and become negatively charged i.e form anions. These ions combine to form stable ionic compounds.

This electron-losing characteristics of metals make them have properties that includes: good conductors of electricity and heat, being lustrous etc.

The freezing-point depression of a 0.100 m MgSO4 solution is 0.225°C. Determine the experimental van't Hoff factor of MgSO4 at t

Andrews [41]

Answer: The experimental van't Hoff factor is 1.21

Explanation:

The expression for the depression in freezing point is given as:

$\Delta T_f=iK_f\times m$

where,

i = van't Hoff factor = ?

$\Delta T_f$ = depression in freezing point = 0.225°C

$K_f$ = Cryoscopic constant = 1.86°C/m

m = molality of the solution = 0.100 m

Putting values in above equation, we get:

$0.225^oC=i\times 1.86^oC/m\times 0.100m\\\\i=\frac{0.225}{1.86\times 0.100}=1.21$

Hence, the experimental van't Hoff factor is 1.21

Why is air considered a mixture not a compound?

blondinia [14]

The best reason I can think of for why we believe that air is a mixture is that freezing air slowly yields different liquids at different temperatures. Liquid nitrogen has a different boiling point than liquid oxygen. They also freeze at different temperatures. If air were only 1 compound, then air in its entirety would have a single boiling point and a single freezing point.
